Saw the movie with the kids over break, just now getting around to adding my thoughts (many of which have already been expressed by others):
The actors playing Rey and Finn were absolutely fantastic. I can't imagine how anyone could have done any better in those roles.
The Ren character came off as a bit of a simpering whiny-butt; but then again, perhaps I went in there expecting another full-fledged Vader after seeing trailers. After a lot of reflection, I like the character and the way he was played. He displayed the pathos that Hayden Craptiansen was completely unable to.
Carrie Fisher clearly did not age nearly as well as did Harrison Ford. Can't yet say about Hamill, though he was smart to grow that beard to hide his crippled face.
Chewie was so damned likable in this movie!
The 40-foot CGI Snoke. First off, that name sucks. Secondly, just stop, Stop, STOP! already with the CGI flesh-and-blood characters intermingling with real actors. It didn't work in Ep 1-3, it didn't work in Lucas' mangling of the original trilogy, it didn't work in any of the Avengers movies, it didn't work in any of the LOTR or Hobbit movies, it just doesn't work (yet). CGI robots, ships, guys in armor suits, OK, maybe. It kinda worked in the full-CGI world of Avatar (until they had scenes with blue folk AND humans in them). Maybe it's good enough for video games or for SciFi original movies, but that kind of technology just isn't here yet for real movies, stop pretending it is.
This movie kinda straddled the line between "reboot" and "remake." I can certainly see why it mirrored the original movies so much...kids today have been HEARING about how great it was to see Ep4 in the theater from their parents for over 30yrs, now they've seen it for themselves. I really like how they managed to keep the dry humor going in this one (instead of just the "dry," like in Ep 1-3). I am really looking forward to more...but I swear I will stop watching if Rey turns out to be the midichlorian-sired, immaculate-conception offspring of Leia's womb (or of Luke's...something...let's not go there!)
So here's something my son came up with: throughout the movie they should have been referring to the data carried in the droids simply as a "clue" to Luke's whereabouts. Then near the end, when the projection is shown, they should have had Admiral Akbar say, "it's a map!" That would have brought down the house!
